Time to time most of my widgets disappear as well. No need to say how annoying is to insert all again. Any way to backup all widgets active and positions?

I know that inside "/home/user/.config/hildon-desktop" we have the some information about the active widgets but If I just backup this folder will do the trick? There is a sql file inside that is a notifications.db inside this folder as well, but I don't know what exactly how it works..
